An apparatus and method for improving use efficiencies of lead-acid batteries, and more particularly to 12V external lead-acid batteries used in vehicles of all types, load-leveling installations, and backup power applications. A method includes the steps of: a) determining a state of charge (SOC) for a lead-acid battery; b) comparing the SOC against a predetermined charge zone, the charge zone having an upper bound no more than about 90% maximum charge and more preferably no more than about 85% maximum charge and the charge zone having a lower bound no less than about 70% maximum charge and more preferably no less than about 75% maximum charge; and c) maintaining a charge of the lead-acid battery wherein the SOC is within the charge zone.
